This invention relates to new and useful improvements in miners lamps,and particularly to the type which employs acetylene gas.

is Great annoyanceisexperienced by the miner, by reason of the cloggingof the, open mg in the burner of l'llS lamp, necessitating V theextinguishing thereof and the cleaning of the said opening. Duringthisoperation the gas-continues togenerate and escape, with the result that,whenthe-lamp is again Other objects and advantages will be ape-i parentfrom: the following description when takeniin connection wlth theaccompanying drawmgs. V Y r In the drawings i p a Figure 1 isa frontelevation of a miners acetylene lamp, made in accordance with'thepresent-invention.

Figure 2 is aside elevation of thesame.

Figure 3 is an enlarged horizontalsectional view on the line 33 ofFigure 1.

Figure 4 is an enlargedgvertical sectional view: on the line H of Figure2. I

Figure 5 isan enlarged horizontal sectional view: showing a modifiedrneans forattaching the reflector tothe larnpbody.

Referring particularly to the accompanying drawings, 10 represents aportion of the body of a miners acetylene lamp, from the front of theupper part of which extends the nipple 11, which is surrounded by thecircular flange 12, spaced a short distance therefrom. Threaded into oneside of this flange is the retaining screw 13. The reflector isindicated by the numeral lt, and has the central opening 15. Disposed atthe rear of the reflector is a transverse elongated housing 16, one endof which is open, as indicated at 17, such housing havinga pluralityof'radi-m' ally extending arms 18, which are terminally secured to therear of the reflector, adj acent the periphery therof. Formed in thefront and rearwalls of the housing 16, in alinelnent 65 t with eachother, and in alinement with the opening 15 ofthe reflector, arethe'openings 19 and 20, and formed on the rear wall oi said housing,insurrounding relation to the opening 20, is a flange 21, whichis adaptedito receive'within the space between the nipple 11, and the flange l2,and to be held by'the said screw 13. The flange-2l is provided; with. asmall recess in one side to receive the inner end of the screw 13, asshown at 22,; whereby to hold the parts together,and to. properlyposition the reflector on the lamp. In the front and rear walls of thehousing 16, at the side of the flange 21', adjacent the open end of thehousing, are the alined openings 23, which receive the pivot pin 24.

The magazine burner is indicated,-. as a; whole, by the numeral 25, andconsists of the metal cup 26 ha ving, a circularseries of v openings inits bottom wall, shown at 271,. and a-plurality of regularly spacedopenings; 28, .initssurrounding flange. Fitted in the cup 26 is a disk29 which has a circular series of minute burner openings 30, registeringwith the before-mentioned openings 27, in. the bottom of the cup, andthrough which the gas flows from, the lamp body,.by means of the nipple11. Through the centers of the; bottom of the cup, and the disk 29 isanopening 31, which receives the pivot pin 24:, when said cup is insertedinthe openend of the housing 16. In the otherend of the housing 'is aleaf spring 32 having a terminal ball member 33 which is arrangedtoienter the peripheral openings 28, successively, as the cup is rotatedin'the housing,and,whereby the burner openings 30 registersuccess sivelywith the opening 15. ofthe reflector; Screwed into the opening 15' is acentrallyi apertured sleeve or bushing-34,,the innerqend- 9 of which isadapted to bear; against theouter face of the disk29, to loclrsaid diskagainst accidental rotation. I

When a] burner opening becomes: clogged, theminen simply unscrewsthefsleeveon bush? ing 34, which releases the cup 26 so that the minermay rotate the latter with his thumb, at the exposed portion of the cupsperiphery, in the open end of the housing, until the ball member 33snaps into the next peripheral opening 28, which disposes another burneropening 30 in position to discharge gas through the opening of thesleeve or bushing 34, which the miner ignites by means of the lightingdevice 35, mounted on the refiector.

As will be clear from the sectional View, Figure 3, the disk 29 iscomposed of two parts 29 and 29", the former being mica,

and disposed against the bottom of the cup 26, and the rear being formedof rubber, preferably soft rubber, which is pressed against the rearwall of the housing 16, and against the adjacent end of the nipple 11,

.when the sleeve or bushing 23% is turned up tightly, thereby holdingthe disk against accidental rotation, and preventing leakage of \Vhilewe prefer to secure the reflector to the lamp body by means of the screw13, we

wish it understood that we may internally thread the flange 12, toreceive therein the externally threaded flange or nipple 21, of thereflector, as clearly shown in Figure 5. Also, we may internally threadthe flange 21 to screw onto the nipple 11.

What is claimed is:

1. A miners lamp including a support having a central opening, arotatable apertured disk mounted at the rear of the support in positionto successively dispose its openings in register with the said centralopening, the disk having peripheral openings, a detent for engagementwith the peripheral openings, and means within the support opening forlocking the disk against accidental rotation.

2. A magazine burner for a miners gas lamp including a support having acentral opening, a casing on the rear of the support, a rotatable diskin the casing having burner openings for successive register with theopening of the support, the periphery of the disk having a recessadjacent each burner opening, a detent in the casing for successiveengagement in the recesses to hold the disk in its different adjustedpositions, and a sleeve threaded into the central opening of the suportfor engagement with a face of the disk to hold the opposite face thereoffrictionally against a wall of said casing.

3. A magazine burner for a miners gas lamp including a support havingalining gas openings, a rotatable disk in the support having a pluralityof burners arranged to be successively registered with said alinedopenings, and means 011 the support for pressing said disk intogas-tight relation to one of said alined openings.

4. A magazine burner for a miners gas lamp including a gas deliveringmeans, a

support mounted on the gas delivering means and having gas openings inreceiving relation thereto, agas burner mounted in the support andmovable into and out of register with said gas openings, and meanswithin one of said gas openings for forcing the burner into gas-tightrelation to said delivering means.

5. A magazine burner for a miners gas lamp including a gas deliveringnipple, a support mounted on said nipple and having gas openingsregistering therewith, a gas burner mounted in the support in gastransferring relation to said gas openings, and means within one of saidgas openings for forcing said burner into gas-tight relation to saidnipple.

6. A magazine burner for a miners gas lamp including a gas deliveringnipple, a support mounted on the nipple and having alining gas openingsregistering with said nipple, a burner magazine rotatable in saidsupport to successively register its burners with said openings, apacking on the magazinc, and means in one of said gas openingsmanipulatable against said magazine whereby to force said packing intogastight engagement with said nipple.

7. A magazine burner for a miners gas lamp including a support havingalined openings, means for attaching said support to the body of a lamp,a disk rotatable in said support, and having burners arranged forsuccessive register with said alined openings, means on the supportengaged with said disk for releasably holding the latter with a burnerin registered relation to said openings, and a sleeve threaded into oneof said alined openings in surrounding relation to the flame issuingfrom said registered burner for pressing said disk into gas-tightengagement with said lamp in surrounding relation to said burner.

8. The combination with the body of a miners gas lamp having a gasdelivering nipple, of a support including a casing mounted on the saidnipple and having a central opening, a rotatable member in the casinghaving a plurality of burners arranged to be successively registeredwith said opening, a packing element on the rotatable memher, and asleeve threaded into said central opening for engagement with saidrotatable member to press said packing element into gas-tight engagementwith said nipple.

In testimony whereof we afiix our signatures.
